Angle(Quaternion, Quaternion)

Returns the angle in degrees between two rotations 
a
and 
b
. The resulting angle ranges from 0 to 180.
public static float Angle(Quaternion a, Quaternion b)

Parameters

a

Quaternion

b

Quaternion

Returns

Type

Description

float

Remarks

Example: Think of two GameObjects (A and B) moving around a third GameObject (C). Lines from C to A and C to B create a triangle which can change over time. The angle between CA and CB is the value Quaternion.Angle provides.

Examples

using UnityEngine;using System.Collections;// Calculates the angle (degrees) between// the rotation of this transform and target.public class ExampleClass : MonoBehaviour{    public Transform target;    void Update()    {        float angle = Quaternion.Angle(transform.rotation, target.rotation);    }}
